I've been wearing these bras for about a year now. I have 3 different styles. The Evelyn is a great everyday bra, the Defy has the best uplift, and the Scoop has narrower straps and is cut deeper across the chest. The Scoop is the only style that doesn't show under wider cut necklines.
I really love these bras but they're not for everyone. There is a definite break in period. I agree that they should be worn a few hours the first few days to get used to the feel. The bras can be warm in the summer because the fabric doesn't breath.
The positive for me is that material on the cups is soft and silky. I really love the lack of hardware. The straps stay in place nicely and the lift is great with NO underwires. The bras are also very easy to launder and dry quickly. They are worth the price to me.
I'm 42 C and wear an XL without the pad inserts.
